Morning Folks.

Had a pretty good leak yesterday (My Fault) so stripped everything down and redone the lines, all sweet now.

Since then the pump as been noisy. I left it over night and made sure there weren't any air pockets etc, but the issue remains.

I dismantled the pump and had a look at the impeller. I noticed there are 2 weights inside, small metal cylinders, I assume these are for Balancing.

One was fine (All the way in) the other was poking its head out of the plastic, So knocked it back in and the noise has went down (A bit).

Are these impellers replaceable, has anyone else had issues with the weights inside working their way out.

Another thought I had was they are not weights, but small pieces of metal holding the top of the impeller in to the base of the plastic for the magnet inside.
Anyone have any ideas on these?

What pump is this? I'm assuming its a DDC as i don't recall a D5 having weights in them.

I have replaced the impeller before
Mine started making a sort of rattling noise
I assume it was unbalanced
Wasn't that specific pump res combo
But probably pretty similar
Luckily I had another pump where the pcb had gone
So took the impeller out of that
